5 Terrifying Statements in the Leaked Climate Report

Most media outlets are focusing on the document's conclusion that it is now "extremely likely"—or, 95 percent certain—that humans are behind much of the global warming seen over the last six decades. But there is much more of note about the document—for instance, the way it doesn't hold back. It says, very bluntly, just how bad global warming is going to be. It gives a sense of irreversibility, of scale…and, of direness.

In particular, here are five "holy crap" statements from the new draft report:

We're on course to change the planet in a way "unprecedented in hundreds to thousands of years." This is a general statement in the draft report about the consequences of continued greenhouse gas emissions "at or above current rates." Unprecedented changes will sweep across planetary systems, ranging from sea level to the acidification of the ocean.

Ocean acidification is "virtually certain" to increase. Under all report scenarios, the acidification of the world's oceans will increase—the draft report calls this outcome "virtually certain." As we have previously reported, more acidity "threatens the survival of entire ecosystems from phytoplankton to coral reefs, and from Antarctic systems reliant on sea urchins to many human food webs dependent on everything from oysters to salmon."

Long-term, sea level rise could be 5 to 10 meters. Journalists are already citing the draft report's prediction that by the year 2100, we could see as much as three feet of sea level rise. But there is also a more long-range sea level scenario alluded to in the draft report, and it's far more dramatic and alarming.

3. This is quite alarming.

But the effects of climate change are already upon us,
and once the methane is released, well, it hardly bears
thinking about.

But it IS the truth.

and I do understand that methane is a much more potent greenhouse gas than carbon dioxide, but couldn't you just burn methane and basically convert it to carbon dioxide and water and reduce the impact?

13. Six of one, half-dozen of the other

You'd change it chemically, but the resulting CO2 would be in the atmosphere much longer - on the order of 100+ years. Methane persists for about 12 years on average.

4. Yes, but WHEN will it happen....?

I had heard dire predictions of the Arctic summer-ice disappearing as soon as 2015, Greenland going into full-on melt, but that doesn't appear to have borne fruit...yet...(hell I thought based on last year's amazing low-ice number we might be ice-free this year if the conditions were similar..)

I'm more concerned with the 'frozen tundra' of Siberia...we at least can get good research on the Arctic/Antarctic/Greenland melts, are we getting numbers that we can trust about Russia and their arctic circle melting?

6. Meanwhile you shill for Apple to sell millions upon millions of unnecessary entertainment devices

that require natural resources to create and even more natural resources to power.

So maybe you should pick what side you're really on?

11. I don't shill for Apple, I don't defend its hoarding of overseas cash, I don't hope for the demise

of Samsung, and I don't under any circumstances post about X when my stated interests are, essentially, NOT X.

Climate change is, indeed, a grave concern. Corporations and governments need disincentives to create greenhouse
gases that may contribute to climate change. However, the OP is on record as saying that Apple's enormous cash
hoard is "not illegal." Neither are the practices that contribute to greenhouse gas accumulation.

The Repubbies really know how to "deal" with a problem. They lie harder and faster.

9m, for instance, floods Bruges, Antwerp, Bremen, and about 80% of the Netherlands; and in England, turns Cambridge and Peterborough into seaports. In Florida, the ocean will reach Lake Okeechobee, and Miami will be part of a new set of Keys.
